The Babylon Viewer aims to simplify a specific but common Babylon.js use case: loading, viewing, and interacting with a 3D model.

/**
 * This block will deliver a property of an asset, based on the property name and an input asset.
 * The property name can include dots ("."), which will be interpreted as a path to the property.
 *
 * For example, with an input of a mesh asset, the property name "position.x" will deliver the x component of the position of the mesh.
 *
 * Note that it is recommended to input the object on which you are working on (i.e. a material) rather than providing a mesh as object and then getting the material from it.
